Characterization of Mesophilic Biodigestion of Cow Dung and Mango Peel in Relation to Bioenergy Batch Study

The purpose of this study was to determine the anaerobic biodegradability potential of mango processing solid waste as well as its methane potential (measured as methane yield) using different mass ratios of mango peel and cow dung. Fruit and vegetable wastes are highly biodegradable wastes that could be used to generate biogas through a biological […]

Application of a Deterministic Distributed Hydrological Model for Estimating Impact of Climate Change on Water Resources in Côte d’Ivoire UsingRCP 4.5 and RCP 8.5 Scenarios: Case of the Aghien Lagoon

The purpose of this study is to assess the impact of climate change on the quantitative availability of the Aghien lagoon, which is located in the northwestern district of Abidjan, Côte d’Ivoire. In the first step, the semi-distributed SWAT (Soil and Water Assessment Tools)-based physical model [1] was calibrated and validated at the monthly time […]

Presence of Strains of Escherichia coli and Staphylococcus aureus Detected in Drinking Water in Lalo, Benin: Assessment of Their Sensitivity to Commonly-Used Antibiotics

Benin has a high coverage rate of improved water sources. However, the vast majority of the population does not have access to safe drinking water at home. In the absence of a home piping system, the population devises methods to ensure that drinking water is available at home. As a result, water is extracted from […]

Analysis of Microbiological Quality of Drinking Water in Lalo Commune, Benin (West Africa)

Although drinking water is widely available in Benin, its quality poses a public health concern. Several artesian wells can be found in the district of Ahomadégbé in the commune of Lalo. Unfortunately, anthropogenic factors have a negative impact on the quality of drinking water in this area. The purpose of this study is to assess […]

Behaviors, Knowledge and Practices of the Population of Ahomadégbé’s District (Municipality of Lalo) in Benin in Connection of Home Water Treatment Methods

Water is an essential resource for life. Access to improved water sources for households in Benin’s district of Ahomadégbé is not a problem because a large portion of the population has access to water. People, on the other hand, consume low-quality water as a result of microbiological contamination during transportation and storage. The goal of […]

Quality of Drinking Water in Benin (West Africa): Analysis of the Potential Use of the “Songhaï” Ceramic Filter

Benin’s public health issues stem from a variety of sources. Domestic water plays an important role in households, but it is contaminated by biological and physicochemical pollutants. Household water purification devices, such as ceramic filters, can be used as a solution. “Filtre Songha” is a ceramic filter that is simple and easy to use and […]

The Population Dynamics of the Luangwa (Zambia) Common Hippopotamus (Hippopotamus amphibius) during the Period 1952 – 2015

The population size of hippopotamus (Hippopotamus amphibius Linnaeus 1758) in Zambia’s Luangwa valley was previously assessed for the period 1976-2008 and repeated 2009-2015, and it was discovered to have reached and maintained a carrying capacity K of 6000 individuals over a 165 km river stretch. The riverbank count method, as used in previous studies, was […]

Game Ranching: A Proven Sustainable Land Use Option and Economic Incentive for Biodiversity Conservation in Zambia

Up until the end of 2012/early 2013, the ten provinces of Zambia were surveyed to determine the number and size of game ranches located in these areas. There are three types of game ranches: 1) 500 hectares as a game ranch proper, 2) 50 – 500 hectares as a game farm, and 3) 50 hectares […]

A Detailed Study: Does the Luangwa Hippo Population Size and Density Distribution Vary between Upper and Lower Study Blocks? What Are the Management Implications of Such Distribution Pattern?

The distribution of the common hippopotamus was studied along a 165-kilometer stretch of the Luangwa River in eastern Zambia. Population growth and decline cause oscillations that have persisted for the last 40 years (1976-2015). The research area was divided into upper (A-D) and lower (E-H) study blocks. Between 1976 and 2015, population data revealed a […]

An Advanced Study on the Impact of Varying Degrees of Underground Accidental Explosions on Underground Pipes by Simulation

The detonation of solid, liquid, or gas explosive materials stored beneath the ground surface causes underground accidental explosions. Underground explosions can occur in both sand and undrained clay, with varying degrees of impact on underground structures. The effects of varying degrees of underground accidental explosions on underground pipes were studied using the ABAQUS numerical code […]
